Abstract
A surgical apparatus for positioning within a tissue tract accessing an underlying body cavity. The apparatus may include a seal anchor member comprising a compressible material. The seal anchor member may be adapted to transition between a first condition for insertion of at least a portion of the seal anchor member within a tissue tract and a second condition to facilitate a securing of the seal anchor member within a tissue tract and in substantial sealed relation with tissue surfaces defining a tissue tract. The seal anchor member may have proximal and distal ends and may define at least one port extending between the proximal and distal ends, the at least one port being adapted for the reception of an object whereby compressible material defining the at least one port is adapted to deform to establish a substantial sealed relation with the object. The at least one port may include an undercut to reduce the likelihood of leaks therethrough.
